MANUFACTURE OF ROLLS.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed March 9, 1906. Serial No. 305,086.

f0 all whom it may concern:

Be it known that we, EVAN EDMUNDS and JOHN H. PENDLETON, both of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in the Manufacture of Rolls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in which Figure 1 is a perspective view illustrating our invention; Fig. 2 is a side elevation illustrating a modification thereof; and Fig. 3 is a longitudinal, vertical sectional view of the modification shown in Fig. 2.

Like symbols of reference indicate like parts wherever they occur.

Our invention relates to an im rovement in the manufacture of rolls and it consists in so forming the wabbler or pinion and securing it to the body of the roll that it may be readily replaced. Heretofore in the manufacture of rolls where the pinions or wabblers have been formed integral with the body of the roll, when the pinion breaks, the roll is useless and can only be thrown onto the scrap heap, thus causing an annual loss of thousands of dollars at every rolling mill lant.

We will now describe our invention so that others skilled in the art may employ the same.

Referring to Fig. 1 of the drawing, 2 represents the body of the roll, and 4, 4 the necks which are on the. roll at each end thereof. The neck 4 is adapted to journal in the housings of the roll. The neck 4 is adapted to receive the pinion or wabbler 5 which is slippedover the neck, said wabbler being provided with a hole or socket therefor, and is, brazed thereto with any suitable brazing material thus forming a pin and socket joint between the roll and wabbler of great strength. Holes 6 extend longitudinally through the wabbler 5 and are adapted to register with holes 7 which are formed in the collar 3 of the roll. Suitable bills are passed through the hole 6 into the ole 7 and are secured by brazing. The bod of the roll 2 may be formed of cast iron whi e the wabbler or pinion 5 is preferably formed of steel, which is thus rolonging the life of the roll. Should any of the teeth of the wabbler or pinion 5 be broken, the broken wabbler may be removed and a new wabbler brazed to the roll in the manner already described. Should both the wabbler and the neck be broken from the body of the roll, the roll may be repaired by slightly turning down the collar 8 and fitting thereon the wabbler 5 shown in Fig. 2, which has a socket portion 8 that fits over the collar 3. In order to secure the socket 8 to the turned down collar 3, suitable brazing material is poured through the cavity 9 that extends from the outer end of the wabbler 5 to the inner end of the socket 8 communicating with the cavity thereof The advantages of our invention will be appreciated by those skilled in. the art. In-

stead of having to throw away the rolls when the pinion thereof is broken the roll may easily be repaired.

Our invention may be employed in the manufacture of new rolls or it may be used in repairing broken rolls in which the pinion originally was formed integral with the body of the roll.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:

1. A roll for rolling mills having a pinion or wabbler separate from the body portion of the roll, said body portion and pinion being united by means of a pin and socket joint, and pins extending from said pinion into said body portion, and brazing material connecting said parts.

2. A roll for rolling mills having a pinion or wabbler separate from the body portion of the roll, and means for connecting said parts, comprising a projection on one part extending into an opening or socket in the other art, and a layer of brazing material located between and uniting said connecting means.

3. In combination, a roll or similar device, a second or additional device adjacent thereto, means for securing said devices together, the said means comprising a'pin secured to one of the said devices and extending into an opening in the other of said devices, another pm extending between said devices and into each of them, a layer of brazing material located between and connected to the ad- 'acent surfaces of the said devices, and brazmg material located between one of the said ins and the walls of the opening in which it is located, the said material being connected to the said pin and the said Walls.

4. In combination, a roll or'siinilar dethe walls of theop'ening'in which the said pin vice, a second or additional device, and is located.

means for securing the said devices together, In testimony whereof, We have hereunto the said means comprising a pin secured to set our hands. 5 one of the said devices and extending into an I EVAN EDMUNDS opening in the other of the said devices, a 1

layer of brazing material located between! and connected to the adjacent surfaces of l Witnesses:

the said devices, and brazing material lo- JAMES K. BAKEWELL, 10 cated between and connected to the pin and C. E. EGGER-S.
